vino-server crashes after connect if resolution has been changed via xrandr

[Andrew Jorgensen]

If you connect to vino after having changed the resolution with "Screen Resolution Preferences" (or xrandr) it crashes the vino server and you have to connect again. This is odd because changing the resolution while connected to vino works fine (the client window is resized also and stays connected).

Dapper, updated daily.

Thanks for your bug. What client do you use? Could you get a backtrace of the crash?
- gdb -p $(pidof vino-server)
(gdb) continue
.. connect to the server to get the crash
(gdb) thread apply all bt

I have had this crash from both windows and linux vnc clients. And even if the client was causing the crash through some bad behavior (which it appears not to be) it would still be a bug in the server to crash.

[Martin Flack (martin-martinflack)]

For me it didn't crash, but it also didn't detect the new screen resolution. I made the resolution one size larger, and connecting on the client from another ubuntu machine just shows me a window that is "too small" (there is stuff cut off on the bottom and right and it does not scroll).

I have also seen the behavior where changing the screen size will simply not be detected but I usually still see crashes as well.

I've forwarded the issue upstream with a debug backtrace: http://bugzilla.gnome.org/show_bug.cgi?id=357778
